Reaction vs. resilience Reaction to disaster is how we have been operating, by declaring emergencies and implementing temporary emergency measures for rapid rebuilding after catastrophic events. This is important , however… Resilience can be created by resolving to move forward proactively for the long term in ways that will increase our ability to strategize, rebuild in better ways, adapt, and better manage resources that stay powered and fully capable when catastrophe strikes again.

North Bay Community Resilience Initiative: Aims • Track, publicize, and support cutting-edge resilience- creating energy efficiency, electrification, and microgrid incentives, plus policy advancements by SCP, MCE, BayREN, BAAQMD, and others. • Procure and develop a database of model structures with “Community Microgrid – ready” designs: For new and retrofit residential, commercial, and municipal bldgs. • Develop “Electrification & Community Microgrid – Ready” (ECMR) document for homeowners and installers • Develop Community Microgrid roadmap beginning with critical facility microgrid pilots such as fire stations, hospitals, and places of refuge. • Position these pilots in areas that are conducive to expansion into Community Microgrids. • Develop all as a model for resilience in rebuilding, and for proactive resilience and community modernization.

Aim 1: Support and promote Advanced Energy Rebuild programs for homes and structures Support for rebuilding with efficiency, electrification, and resilience • Sonoma Clean Power (SCP) and MCE Advanced Energy Rebuild: SCP, MCE, Pacific Gas and Electric Company (PG&E), and Bay Area Air Quality Management District have joined efforts to help homeowners affected by the firestorms to rebuild energy-efficient, sustainable homes. • The SCP program offers two incentive packages tailored to Sonoma and Mendocino Counties. • Each package has a flexible performance pathway or a simple prescriptive menu. SCP offers up to $17,500 in incentives to electrify, add solar + energy storage, Connected EV’s, and upgrade to “connected” appliances • MCE has similar “Advanced Energy Rebuild” program for the Napa fire rebuilding efforts.

Aim 2: Model Structures: Advanced Energy Rebuild homes Showcase and provide case studies of homes being rebuilt utilizing the Advanced Energy Rebuild program. Up to $17,500 incentives from Sonoma Clean Power and MCE, to go “all electric” and “microgrid ready” Having a “microgrid” means when the power goes out, your power stays ON Hirsch solar-powered esidence Mini-split heat pump H.P water heater L.G. Chem energy storage Induction cooking Making Clean Local Energy Accessible Now 8
Aim 3: Model structures Developing a design database for model structures for new and retrofit residential, commercial, and municipal buildings • In collaboration with high “performance based” building organizations in the USA : • US DOE Zero Energy Ready Home Program & US DOE “Solar Decathlon” homes database • Passive House Institute US • USGBC / New Buildings Institute “Grid - Optimal” • Net Zero Energy Coalition • Rocky Mountain Institute Making Clean Local Energy Accessible Now 9
Electrification & Community Microgrid – Ready (ECMR) specifications document • Developed by the Clean Coalition and a team of industry experts, as a guideline for homeowners and trades installers to easily install necessary wiring to be all-electric and microgrid-ready. • All-Electric benefits; Safer and healthier homes and communities ; • Elimination of natural gas which is highly flammable, and produces formaldehyde and other toxic gases within the home and community • EV adoption = Reduction and eventual elimination of all fossil fuels • EV’s can become “mobile energy” assets, saving and making money • Reduced reliance on outside fuel & energy sources • Reduction of greenhouse gases • REVENUE for homeowners by using your connected assets as grid assets • Microgrid benefits; Energy resilient homes and communities • Ability to stay powered in grid outages = Resilience and Security • Ability to use behind the meter and community energy storage as “grid assets” = revenue stream • Energy produced by local renewable sources = local jobs Making Clean Local Energy Accessible Now 10
Resolution for Resilient Cities • Drafted and intended as a statement of intention by a city, municipality, or region toward developing resilient infrastructure and buildings. • Santa Rosa and Calistoga may be first adopters • Open source and available to all civic and municipal bodies interested Making Clean Local Energy Accessible Now 11
Nanogrids, Microgrids, and Community Microgrids Nanogrid: A single site (residential) microgrid; single physical layer of power distribution with a localized energy control system, creating reliability, quality, and site based capacity. Coordinated behind-the-meter (BTM) site based renewable energy, and energy storage. It can be islanded (from the local grid) at the customer meter. The key attribute of a nanogrid is simplicity . Microgrid : A coordinated set of behind-the-meter (BTM) local renewable energy, energy storage, and other Distributed Energy Resources (DER) on a building or campus scale , that can be islanded (from the local grid) at the customer meter. Community Microgrid : A coordinated set of local renewables, energy storage, and other DER that can also be islanded, (from the larger grid) across a defined distribution grid area to provide indefinite renewables-driven resilience to critical community facilities, and other structures within the community.

Benefits of nanogrids Financial impacts of building or unit-scale nanogrids • Lower operation costs (near “0” energy bills) • Revenue from excess energy export (HOA dividends ?) • Renewable transportation energy – (100% R.E. EV charging) • All electric and “tighter” buildings = better I.A.Q. = healthier homes • Energy “resilience”, and fire “resilience” (with fire resistive materials) • Home is a community resilience asset / and a grid asset • Elimination of fossil fuels (reduced GHG emissions ) • Safer buildings and communities = Higher appraised property values Making Clean Local Energy Accessible Now 13
Critical-facility microgrids • Critical-facility microgrids ; “Island” from the Grid in the event of grid outage or disruption to power critical loads for community services, safety, and security. They include renewable energy, and energy storage assets: Kaiser Permanente Richmond Microgrid • Hospitals : Kaiser Permanente Richmond Microgrid • Fire Stations : City of Fremont Fire Station Microgrid Freemont Fire Station MIcrogrid • Emergency shelters : Seattle Community Center Microgrid Seattle Community Center Microgrid • Campus microgrids: Stone Edge Farm Microgrid Stone Edge Farm Microgrid Making Clean Local Energy Accessible Now 14

Community Microgrids can serve up to thousands of “prosumer” and “consumer” utility customers Prosumer ”: Utility customers that both produce energy for and consume energy from the grid or microgrid “PROSUMERS” CRITICAL FACILITY MICROGRIDS “PROSUMERS” Making Clean Local Energy Accessible Now 16
Community Microgrid benefits • Reliability and power continuity • Local control of energy • Permanent local jobs in energy, installation, and maintenance • Local energy for EV transportation systems • Network of prosumers share the use, generation, and revenue of and from energy. • No “peaker” power plants • Reduced transmission losses • Enhanced safety • GHG reductions • Resilience and energy security • National security • Reduced global conflicts CEC California microgid roadmap • Peacetime infrastructure spending Making Clean Local Energy Accessible Now 17
